Which one of these characterizes a hydrophilic substance, a substance that is easily mixed with water?

select one of the options below as your

a. substances that are polar in nature
b. substances that are nonpolar in nature
c. substances that are inert in nature

A polar molecule has a net dipole as a result of the opposing charges from polar bonds arranged asymmetrically. The dipoles do not cancel out resulting in a net dipole. Due to the polar nature of the water molecule itself, polar molecules are generally able to dissolve in water. So the right answer is A.

answer: - b cells

explanation: -

there are many types of white blood cells present in our body. one such class of white blood cells are the lymphocytes. the b cells belong to the lymphocyte class of wbcs. the b cells perform their action against the pathogen by producing specialised proteins called as antibodies. these antibodies are produced as and when the b cells encounter pathogens in response to the antigens present on the surface of the pathogen. these antibodies bind to the antigens present on the pathogen and then, target them for destruction by other cells of the immune system.

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.
